Sonic 1 Disassembly

sorry for double posting, but the edit button isn't showing up at the moment, anyone know why?

anyway, the only tiles recognisable were the font tiles, all the others were crazy, possibly because the palette was wrong. is there any way of loading a palette in bin format? when I edit the tiles, how do I un-'split' them? if you get me.

 

To "un-split" them, as you put it, you run the build.bat file.

when I did, the s1build.bin file didnt do anything in gens it just stayed black

o right ok

 

I have no idea how to do ASM (well, I know about 1/2000th of the knowledge you'd need) BUT this seems like a great way to learn. Thanks.

 

I'm having trouble building it - I've created a blank file named "s1comb.asm" so include.exe doesn't fail, and I click build.bat, and I get a >1kb .bin ROM file made that's corrupt.

The generated s1comb.asm file is 1,216 kb, and when I added a pause in the bat file after snasm68k was run, it says there were 423 errors. It shows the last few errors, saying it can't find anything referenced by the incbin commands.

Any help?

 

...did you split a ROM named "s1.bin" yet? That kinda sorta would have all the data you're missing, there.

 

Whoops - forgot to read the readme file - thanks!

EDIT: Out of curiosity - in the bat file - what's the point of recompressing? The ROM generated is 512kb like the original retail - does recompressing make the size smaller? Or leave more extra space with no purpose?

 

Hivebrain, would you mind if I released a version of this disassembly for Mac and Linux? (with the appropriate changes for it)

 

I prepared a while back project files fixed for the files named in Hivebrain's disassembly; I can't wholly guarantee that they work, but they'll do.

WARNING: merge GHZ graphics before trying anything with these - they expect a file in artnem called 8x8ghz.bin.

 

After adding a stopping frame and changing the sign post and life icon art, I rebuilt the rom, creating s1built. The sega sound plays fine up until the end, when static is played. How do I fix this?

 

I'm having a problem with it too. When I run build.bat I don't get the s1comb.asm, all it outputs is the binary, which is 128 bytes. And I have got all correct stuff in there, like folders ect, and the split the rom files.

 

Oh cool thanks.

 

Any news on this? I'm sure it beats the hacked-together method I'm using =P (snasm68k in DOSBox, everything else in Wine)

 

Right, I might as well do it.

First you'll need to compile and install this assembler (A simple "make"/"make install" should do it).

Then, download the patched disassembly here and run the build.sh shell script to compile.

The mentioned disassembly archive includes Hivebrain's disassembly, with all the include paths changed to use / instead of \ on the paths, and with the "; include=" includes changed to standard "include" directives. I also patched out the checksum check, since there is no linux version of "fixheadr.exe". It also has the stuff from a sonic 1 rom pre-split, as there's also no linux version of "split.exe". Have fun.

 

Cool, thanks!
Also, the hacked-together (and sloppily written) method I mentioned myself using can be found here, for those who want something more true to the Windows version I guess =P
